I grew up in a house with a whole house fan, and no air-conditioning. The fan was great when the
temperature went down into the 60’s at night, it pulled cool air throughout the entire house and cooled it down quite nicely. It even helped after those scorching hot days when the temperature only dropped to the mid 80’s at night, it kept a gentle breeze flowing throughout the house all night. I’m sure it saved my parents hundreds of dollars even back then, and installing one in your house can save you up to 50% on your cooling bills every year or up to 90% if you eliminate conventional air conditioners all together.
One of the great benefits of whole house fans is that they will cool your house to a lower temperature than an air conditioner will when the temperature outside at night drops lower than the temperature
that your air conditioner is set to. Thus, not only will it suck the hot air out of your house, but it will also suck some of the heat absorbed in the walls, floors and ceilings out of your house out too. Then in the morning, when the temperature is the lowest, close all of the windows in order to keep the heat of the day out. In this way you will start the day with a nice cool house that can absorb a fair amount of heat as the temperature climbs outside before the interior starts to become uncomfortable. The more thermal mass such as masonry or plaster walls, concrete, hardwood and/or tile floors that a house has, the more heat it can absorb during the day and be exhausted by the fan at night.
The two possible downsides to a whole house fan are the noise of the fan and t
he introduction of allergens into the house. The fan we had growing up provided a constant hum that just became a nice background noise and actually helped to put me to sleep. Many of the fans available today are quieter than those made in the past, and many of them have a low speed setting so that they operate even more quietly. With respect to allergens, if someone in the house has a problem with seasonal summertime allergies then you probably shouldn’t consider a whole house fan.
Two precautions that you should take are to and to seal all of the holes and cracks between the house and the attic and to make sure that you have adequate ventilation form your attic to the outside. There should be about one square foot of clear vent space to the outside from the attic for every 750 cfm of fan volume. If these precautions are not taken the fan will push hot dusty air right back in to your house.
Conserve energy and enjoy natural cool night breezes this summer. Turn off your air conditioner, and save hundreds of dollars by cooling your house with a whole house fan.

If you would like to improve your indoor air quality the natural way there are some house plants that will do a much better job than others. Some of these plants do a great better job at converting carbon dioxide to oxygen, while others help to remove harmful elements such as trichloroethylene, benzene, formaldehyde and other volitile organic compounds (VOC’s). Some of the best plants for this are: English Ivy, Spider plant, Devil’s ivy, Peace lily, Chinese evergreen, Bamboo palm or reed palm, Snake plant or mother-in-law’s tongue, Heartleaf philodendron, Selloum philodendron, Elephant ear philodendron, Red-edged dracaena, Cornstalk dracaena, Janet Craig dracaena, Warneck dracaena, Weeping Fig, Gerbera Daisy or Barberton daisy, Pot Mum or Florist’s Chrysanthemum, and Rubber Plant.
We spend most of our lives indoors, and the majority of that indoor time in our homes. The concern for energy conservation has lead to houses that do a much better job at keeping the cold outside air out. This has done wonders for the energy efficiency of our homes, but has lead to one unfortunate consequence: poor indoor air quality. In old leaky homes, any contaminants inside the house would typically be blown right back out of the house, but in newer homes they can easily become trapped inside.
Some of these contaminants can lead to increased short term allergic type reactions and symptoms like irritated eyes, nose and throat, dizziness and fatigue. These short term reactions are typically not serious health concerns, but some indoor air contaminants have been linked to long term and serious conditions such as respiratory disease, heart disease, and cancer. It is difficult to pinpoint what level of exposure to these contaminants is potentially dangerous, and it also seems to vary from person to person. However, whether you suffer from short term reactions or are concerned about the potential dangers of long term exposure here are ten ways to control indoor air contaminants at their source:
- Leave your shoes at the door: The soles of your shoes can track numerous types of contaminants into your house like tar, dirt, feces, sticks, leaves, road salt, oil, and numerous types of chemicals found on our streets, sidewalks, parking lots and driveways.
- Chemical free cleaning: Eliminate potentially harmful chemicals from your house and improve the indoor air quality by switching to natural, organic cleaners and/or cleaning cloths made of mirafibers which only require water to clean just about anything. These incredible cleaning cloths will also help you save on paper towels too.
- Purchase formaldehyde free and low VOC (volatile organic compound) products: Many building products have traditionally been made with chemicals that have been shown to produce negative effects in some people. These include fiberglass batt insulation, engineered wood products like plywood and particle board, paints, adhesives, varnishes, polyurethane, and carpeting.

- Quit smoking or smoke outside: Second hand smoke is a proven carcinogen, not to mention the foul odor that it leaves behind.
- Provide adequate exhaust for combustion sources: Stoves, ovens, furnaces, fireplaces and kerosene heaters that are improperly vented can introduce dangerous levels of carbon monoxide gas into your house. Carbon monoxide is poisonous, and especially dangerous since it is colorless and odorless.
- Contain the mess or take it outside: Many hobbies and home improvement activities like soldering, gluing, woodworking, sawing, furniture refinishing and sanding can create a huge mess and that mess can quickly spread throughout your house. Several ways to minimize this are to turn off your furnace while you are working, clean up as soon as you are finished, install an automatic vacuum system in your wood shop, or simply do the project outside.

- Keep the pests under control: A clean house that is well sealed to the elements will also keep pests like ants, cockroaches, mice, and other vermin from coming into your house, bringing various contaminants along with them. Properly storing dry goods in sealed containers will also help to keep the pests away.
- Moisture control and mold prevention: Mold will thrive in warm, moist environments wherever there is a “food” source like paper, wood, or other organic material. Keep a watchful eye out for any water leaks indoors and out, and fix any problems immediately.
- Weatherize your home: Sealing all of the cracks and holes on the outside of your house will also keep many pollutants from ever coming into your house.
- Keep the beach and the pool outside: The chlorine laden pool water in your suits and towels should stay outside along with the sand form the beach. Line dry your suits and towels outside and then toss them in the washer as soon as possible.
The first step to improving the quality of the air in your house is to stop the contaminants at their source. Following these ten steps will help you keep the inside of your house cleaner, limit your exposure to potentially harmful substances and can even improve your health. Keep these pollutants under control and breathe easy.

In a desperate attempt to reduce the work involved by having to replace mulch every year in my flower garden, I began to do some research on rubber mulch. What I found is that there has been lots of controversy about having rubber mulch around your garden because, according to some gardeners, rubber mulch may leach chemicals that could kill your plants. In a report written in 1997 by Rufus Chaney, who is an environmental Chemist for the U.S.D.A. Agricultural Research Service, he says that in his studies, small amounts of zinc in rubber mulch could leach into the soil over time.
The next report I read came from the U.S. Consumer Product Safety Commission which tested gravel, wood chips, and rubber mulch and they gave rubber mulch the highest shock absorption ratings when used as playground covering. This is good news for parents and teachers alike as it will provide safety and minimize the cuts and bruises children get while at playgrounds.
Several other studies that I read stated that rubber mulch is non-leaching, non-flammable and non-toxic to plants, animals and pets. The problem with these studies is that these were done and sponsored by the companies that process the mulch so I do not know if we should believe this or not. And, the arguments continue between the environmental agencies and the companies that manufacture rubber mulch.
So, we now know that rubber mulch is good if used in playgrounds and other non-garden related areas, but what about a flower garden? First, take a look at what rubber mulch is. It is made from old rubber tires that had the steel bands removed. It does not matter the size, quality or make of the tire, any old tire will do. It does not matter if the tire came from a truck or a passenger car. The rubber from these tires is then made into nuggets thus creating rubber mulch. Next, we will discuss the advantages and disadvantages of using rubber mulch.
Advantages
• it is recycled material which benefits the environment
• it insulates the soil protecting it from heat
• does not absorb water so it keeps the soil moist
• prevents weeds since seeds will dehydrate in the mulch prior to reaching the soil
• shredded rubber mulch can be used as landfill
• does not wash away during heavy rain
• does not decay
• does not sink to the ground
• does not attract termites, ants and other garden insects
• can be purchased in different colors to add beauty to a garden or landscape
• no need to remove old mulch year after year from the garden
• saves time and money tending to garden needs
Disadvantages
• it is more expensive than regular wood mulch
• may leach chemicals into the soil
• does not provide soil with any organic matter
• some gardeners have reported that it killed some of their plants
• may produce bad odor when spread in the garden
By reviewing the lists above, it is obvious that the advantages of using rubber mulch are much greater than the disadvantages. But, should we take a chance and use it on our flower gardens? That is a decision that each individual gardener needs to make.
As for me, I took a chance and bought rubber mulch in March of this year and replaced the old wood mulch in my flower garden. I must admit that I was a little nervous at first, but it was a time and money saving decision that I had to make. I expected some bad odor to permeate all around my garden, but there was none. Time will tell if the rubber mulch will damage some of my plants but so far, my flower garden is doing well and the rubber mulch looks great.
